Abstract

A dual-band GPS receiver and method and apparatus for downconversion of dual-band GPS signals. A dual-band GPS receiver in accordance with the present invention comprises an antenna, a Radio Frequency (RF) section, coupled to the antenna, and a baseband section, coupled to the RF section, wherein the RF section comprises a receiver, the receiver receiving signals from a first GPS frequency band and a second GPS frequency band, a local oscillator having a local oscillator frequency, and a mixer, coupled to the receiver and the local oscillator, for selectively mixing the local oscillator frequency with the first GPS frequency band and a second GPS frequency band, wherein the local oscillator frequency downconverts the first GPS frequency band and the second GPS frequency band into a common downconversion frequency band.
